RECLAIM – Water Reclamation Technologies for safe Artificial Groundwater Recharge

A Specific Targeted Research Project under the Thematic Priority 'Global Change and Ecosystems', EU 6th Framework Programme.

Coordinator: RWTH Aachen University

Timeframe: October 2005 – January 2009

Solutions to global water stress problems are urgently needed yet must be sustainable, economical and safe. The utilization of alternative water sources like reclaimed municipal wastewater is one of the most obvious and promising options in integrated water management. Among the various beneficial uses of reclaimed wastewater the artificial recharge of aquifers receives growing attention because it features advantages like additional natural treatment, storage capacity to buffer seasonal variations of supply and demand as well as mixture with natural water bodies which promotes the acceptance of further uses, particularly of indirect potable use. Major concerns about the safety of this exploitation route of an alternative water source are connected to microbial and chemical contaminants occurring in wastewater, among which are emerging trace organics like endocrine disrupters and pharmaceuticals.

The strategic objective of this proposal is to develop hazard mitigation technologies for water reclamation providing safe and cost effective routes for artificial groundwater recharge.

RECLAIM WATER will assess different treatment applications in terms of behavior of key microbial and chemical contaminants. The knowledge generated in this project and the technologies developed will be also partly suited to the needs of developing countries, which have a growing need of supplementation of freshwater resources.

The proposed project will strategically support the competitiveness of European technology suppliers and water services in the context of water reclamation and groundwater recharge.

RECLAIM WATER will provide effective technologies to monitor and mitigate emerging risks posed by chemical contaminants and pathogens in reclaimed wastewater streams. The project main results will be:

The data basis necessary will be generated in a set of case studies. These will also serve to validate the concept, prove its practicability and effectiveness, take into account regional and use type variety and – as a by-product – to assess a number of selected treatment processes.
